30 days hath September, April, June and November. All the rest have 31 except for February.
There are 4 months with exactly 30 days, and 11 months with 30 or more (30 or 31).Only February has just 28 days (29 in leap years).April, June, September, and November have 30 days.March, May, July, August, October, and December have 31 days.
there are 4 months a year that have 30 days; in four years that is 4 x 4 = 16 30 day months
"30 days has September, April, June, and November..."
The riddle answer is "12." -- all 12 of them have at least 28 days.Only February, in years that are not leap years, has exactly 28 days.Of the others, 4 have 30 days and 7 have 31 days.(see related question)
4
4 months of the 12 months have 30 days April, June, September and November 4/12 = 1/3 of the year
Approximately four weeks. There are 31 days in most months, so that is 3 days more than 4 weeks. Four of the months have 30 days, so that is 2 days more than 4 weeks. One month has only 28 days, which is exactly four weeks.
Exactly 48 months. The period 1461 days is exactly 4 years (three years and one leap year). In this case, you do not have to use the average for days in a month (30.4 days).
more than 4 less than 5 months usually have 30 or 31 days 146/30 for example = 4.87 months slightly less if 31 days so about 4 months 3 weeks
About three months, because there is 30-31 days in a month.
There are 30+31+30+31 = 122 days in the last four months of the year.
